Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to a semi-worsted cashmere hollow yarn structure with good air permeability. Background Technology

[0002] Cashmere fiber, as a high-end weaving material, is increasingly favored by consumers for its high quality and excellent performance. Fabrics made from cashmere yarn are soft to the touch, warm, and comfortable to wear.

[0003] Traditional cashmere yarn has poor breathability due to its fine fiber size and tightly packed scales.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a semi-worsted cashmere hollow yarn structure with good breathability to overcome the shortcomings in current practical applications. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a semi-worsted cashmere hollow yarn structure with good breathability, aiming to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A breathable semi-worsted cashmere hollow yarn structure includes a moisture-wicking and breathable layer, an elastic support layer covering the outer wall of the moisture-wicking and breathable layer, and a breathable protective layer covering the outer wall of the elastic support layer. The moisture-wicking and breathable layer includes profiled polyester filaments and a first cashmere fiber, with the outer wall of the profiled polyester filaments covered by the first cashmere fiber. The elastic support layer includes hollow polyester fibers and a second cashmere fiber, which are twisted by a spiral winding method. The breathable protective layer is a mesh structure formed by blending a third cashmere fiber and bamboo fiber.

[0008] In a further technical solution, the cross-section of the profiled polyester filament is Y-shaped, and the outer wall of the profiled polyester filament is provided with microgrooves.

[0009] In a further technical solution, the hollow polyester fiber has a C-shaped cross-section.

[0010] A further technical solution is that the breathable protective layer is formed by blending third cashmere fiber and bamboo fiber with a fineness of 15.5-16.5μm.

[0011] In a further technical solution, the surface of the breathable protective layer is treated with bio-enzymes.

[0012] In summary, the embodiments of this utility model have the following beneficial effects compared with the prior art:

[0013] The Y-shaped cross-section and microgroove design of the profiled polyester filament significantly improves the moisture conduction efficiency, effectively solving the problem of poor moisture conduction performance of traditional polyester fibers. The hollow polyester fiber and C-shaped cross-section form a longitudinal air-permeable channel, enhancing the elasticity and breathability of the yarn. The mesh structure formed by the blending of third cashmere fiber and bamboo fiber improves the yarn strength and abrasion resistance while maintaining good breathability.

[0014] By combining a moisture-wicking and breathable layer, an elastic support layer, and a breathable protective layer, a semi-worsted cashmere hollow yarn with a multi-layer structure is formed. This not only solves the performance limitations of a single material, but also improves breathability, elasticity, abrasion resistance, and comfort through the synergistic effect between the layers.

[0015] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0020] like Figure 1 As shown, this utility model embodiment provides a semi-worsted cashmere hollow yarn structure with good breathability, including a moisture-wicking and breathable layer 1. The outer wall of the moisture-wicking and breathable layer 1 is covered with an elastic support layer 2, and the outer wall of the elastic support layer 2 is covered with a breathable protective layer 3. The moisture-wicking and breathable layer 1 includes profiled polyester filament 11 and a first cashmere fiber 12. The outer wall of the profiled polyester filament 11 is covered with the first cashmere fiber 12. The elastic support layer 2 includes hollow polyester fiber 21 and a second cashmere fiber 22. The hollow polyester fiber 21 and the second cashmere fiber 22 are twisted by a spiral winding method. The breathable protective layer 3 is a mesh structure formed by blending a third cashmere fiber and bamboo fiber.

[0021] Furthermore, the profiled polyester filament 11 has a Y-shaped cross-section, and the outer wall of the profiled polyester filament 11 is provided with microgrooves. The microgrooves increase the surface roughness of the profiled polyester filament 11, forming more capillary channels. These channels provide a fast conduction path for moisture, accelerate the diffusion and evaporation of moisture, and help keep the skin dry and comfortable.

[0022] Furthermore, the hollow polyester fiber 21 has a C-shaped cross-section. The hollow structure makes the fiber lighter and allows it to store more air, while also providing good elasticity and resilience. The C-shaped cross-section design not only increases the fiber's bulkiness but also makes it easier for the fiber to form longitudinal air channels during twisting, which in turn helps improve the fiber's elasticity and resilience.

[0023] Furthermore, the breathable protective layer 3 is formed by blending third cashmere fiber and bamboo fiber with a fineness of 15.5-16.5μm. The bamboo fiber content is 10-20% of the moisture-wicking and breathable layer. A dense mesh structure is formed by a semi-worsted spinning process. The dense mesh structure enhances the strength and abrasion resistance of the yarn, making the textile more durable. At the same time, this structure also helps to improve the warmth and breathability of the textile because the gaps between the fibers can store air and allow moisture to pass through.

[0024] Furthermore, the surface of the breathable protective layer 3 is treated with bio-enzymes, which can remove impurities from the fiber surface and improve the feel and appearance of the fiber. In addition, the scale layer of cashmere fibers may increase the coefficient of friction between fibers, causing the textile to pill easily during wear. Through bio-enzyme treatment, these scale layers can be removed or softened, thereby reducing the coefficient of friction between fibers.

[0025] In this embodiment of the invention, the Y-shaped cross-section and microgroove design of the profiled polyester filament 11 significantly improves the moisture conduction efficiency, effectively solving the problem of poor moisture conduction performance of traditional polyester fibers. The hollow polyester fiber 21 and C-shaped cross-section form a longitudinal air-permeable channel, enhancing the elasticity and breathability of the yarn. The mesh structure formed by the blending of the third cashmere fiber and bamboo fiber improves the yarn strength and abrasion resistance while maintaining good breathability. The combination of the moisture-wicking and breathable layer 1, the elastic support layer 2, and the breathable protective layer 3 forms a semi-worsted cashmere hollow yarn with a multi-layer structure, which not only solves the limitations of single materials in terms of performance, but also improves breathability, elasticity, abrasion resistance, and comfort through the synergistic effect between the layers.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
